Array of randome objects along a curve?

Unread postby kirkr22 » Wed Nov 11, 2020 10:42 pm

How can I do it in Clarisse? I see I can import a curve as vertexes only and use them to scatter objects but how could I make them follow the curve ? getting right rotation values? Is there any other approach to do so? An array of curb stones along a road for example with some procedural control over randomness?


ps. Found a way actually with not a vertexes only "curve" but rather a polygonal stripe and point cloud set to be using "Primitive center". Looks like points gets the rotation value from the polygons . Is it the right way for doing it?

Hi,

Yes for now the polygonal stripe is the solution. In SP13 you will be able to do it with the curve directly with a secret node ;)

Now with a sp13 out can we have an example how to do it please?

Hi,

the new secret tool in 4.0 SP13 is the "Curve Utility" in your Material Editor > textures > Utility.

Just import a curve, create a point cloud and a scatterer.
Now you need to plug to the "scatter rotation" these nodes :

Be sure to have the rotation on each axis set to 360.

I also a small for you to check the set-up.

Enjoy

The way is useful.
But I want to array of randome objects along many curves at once, how to do that?
I import two curves which are from 3dsmax. (the two curves are attach into 1 geometry in 3dsmax, but it become to 2 geometry when it's imported in clarisse.)

How to array of randome objects along this two curves at once?
Are there some ways to make many curves become 1 geometry when they are imported in clarisse.
Why the curves in your "curves.project" are "SceneObject", and the curves in my project is "GeometryAbcFur"?

Looking forward to your guidance. thanks.

Hi,

Yes in this case you can select only the first curve in your alembic reference. You can submit a feature request for this in the support page.

In the meantime, you can add all the curves into a new combiner and load this combiner into your point cloud. Now Clarisse is spawning particle along all the curves.

It seems that in some case,particle can't spawn along all the curves.

Hi,

I was able to reproduce your example and have the same issue.
Can you please fill a bug report here https://www.isotropix.com/user/bugtracker-new
Not ideal but for now you need to generate one point cloud per curve.

Cheers.
